Abstract
1482353 Temperature compensated transducers PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 30 Aug 1974 [4 Sept 1973] 38030/74 Heading G1N A transducer element C, e.g. a zirconium oxide partition measuring the ratio of partial oxygen pressures on respective sides of the partition in the temperature range 450-850 degrees centigrade, producing a D.C. output voltage dependent on a quantity to be measured and also on temperature and having a temperature-dependent internal resistance is connected in a circuit which utilizes this resistance to effect compensation of the output e.m.f. for temperature variations. In one embodiment, Fig. 2, the element is connected in a voltage-divider with a resistance 3 and the divider is supplied by a constant amplitude square-wave source 4 to provide a temperature-dependent A.C. signal at terminal 8. This A.C. signal is removed in a low pass filter 10 and the D.C. signal fed to one input 29 of a divider or multiplier 28. An A.C. amplitude detector 11 is also connected to terminal 8 and which includes a D.C. blocking capacitor 16, and peak rectifying diode 17. The resulting D.C. voltage V 1 3 on line 13 varies as a function of temperature as the line (L 1 ) in Fig. 5 (not shown). Inverting amplifier 20 produces a voltage which is directly proportional to temperature which is fed to the other input 30 of the divider which produces at terminal 15 a D.C. output depending only upon the quantity to be measured. Alternatively, Fig. 3, the low pass filter 10 connected across the element to supply only the D.C. signal from the element to a chopper circuit 33, 34. The resulting A.C. signal is amplified 37 and supplied across a voltage-divider consisting of resistances 42, 43, blocking capacitor 44 and the element C. The resistances 42,43 are chosen with respect to the internal resistance of the element so that the voltage-division is inversely dependent on absolute temperature. As a result the alternating voltage output from the divider at terminal 9 represents the quantity to be measured only, that is, the temperature-dependance is compensated for, at least, within the range 450-850 degrees. The resistor R42 is from 0À3 to 0À6 times Ri at the centre of the range where Ri is the internal resistance of the element and R43 is from 0À6 to 0À8 Ri. Reference is made to measuring temperature per se and to measuring mechanical stress using a Piezo-electric element.
